Can there please be an honest response as to why fundamental problems such as these aren't where your development resource and effort is being applied? Why put this effort into Dark Mode - a feature that's only available in the latest version of macOS - when Spotlight integration has been broken for such a long time? See also my previous comment about the search highlighting problem.
This is a bad one, especially as it was acknowledged in an earlier beta as something that has an "open ticket with the engineering team". It's a showstopper for me, and I'm somewhat amazed it made it through to the release - it's surely a blocker, unless you have questionable priorities.
